What's the Best Method to Communicate Data Graphically?: An Experiment in Visual Perception

Science Fair Project Idea

Scientific Method

Graphical methods of data presentation are a key feature of scientific communication. This project will get you thinking about how to find the best way to communicate scientific information. Read more

Preventing SQL Injection Attacks

Science Fair Project Idea

Engineering Design Process

How many websites do you have accounts with that store personal information like your name, email, phone number, or mailing address? If the people running these websites are not careful, hackers could gain unauthorized access to, and even change or delete, your information. They can do this using something called SQL injection, which involves entering malicious code into text fields on a website. In this project you will learn how SQL injection works and figure out how to prevent it. Read more

Sound Localization

Science Fair Project Idea

Scientific Method

How accurately can people identify the location of a sound source when blindfolded? Imagine the hemisphere of space that extends above your shoulders at arm's length. Divide that hemisphere up into regular sectors and test the ability of blindfolded test subjects to point to a remembered sound source. For example, you could use the beep from a timer held at each test location, and then have the test subject point to where they think the timer was located. Record the magnitude and direction of… Read more

Program to Check (or Solve) Sudoku Puzzles

Science Fair Project Idea

Engineering Design Process

Sudoku is an extremely popular puzzle game. You start with a 9x9 grid of squares, which contains three smaller 3x3 subgrids. Some of the squares are filled in with numbers 1 through 9. Your goal is to fill in the remaining blank squares such that each column, each row, and each 3x3 subgrid contains the numbers 1-9. No number can appear more than once in any column, row, or subgrid. For a given starting puzzle, can you write a program to check if a Sudoku solution is valid using a programming… Read more

Eco-Friendly Squishy Robots

Science Fair Project Idea

Scientific Method

In our introductory VoxCAD project, you were challenged to use the VoxCAD software to design the fastest possible robot using different materials. However, we did not ask you to think about one big thing — efficiency. It is great to design a robot that is very fast, but what if it also consumes a lot of energy? Engineers must consider this when designing robots in the real world — robots that use more energy to move will drain their batteries faster, which can be a problem. This is… Read more

What Electric Bills Can Tell You About Energy Use

Science Fair Project Idea

Scientific Method

This project is a great way to "bring home" the concept of energy use. All you need to get started is a good-sized sample of monthly electric bills from households in your area. Building from this simple beginning, you can ask questions that can take you in many different directions. For example: How much electricity does the "average" person in your area use per month? How much does electricity use vary among different families? Read more

Candy Confusion: Can Small Children Mistake Medicine for Candy?

Science Fair Project Idea

Scientific Method

Many medicines come in bottles with special child-proof caps so that small children can't accidentally open the bottle and eat the pills. To a small child who can't read the label, the pills might look just like candy. What cues do we use to tell the difference between medicine and candy? At what age can we tell them apart? This project can show you how to find out. Read more

Only If They Think They Can Get Away with It?

Science Fair Project Idea

Scientific Method

How many times have you seen a car without the appropriate permit (either a license plate or placard that hangs from the rearview mirror) parked in an accessible parking space reserved for people with disabilities? If you find this behavior upsetting, you might be interested in figuring out how to discourage "cheaters" who use these spaces to make a quick trip into the store. Is it enough to let them know someone might be watching? Read more

Get Saucy with the Thickening Power of Starches

Science Fair Project Idea

Scientific Method

Who doesn't love soaking up the last bit of gravy on Thanksgiving? Or dipping a crusty cube of bread into a cheese fondue? Or scooping up the thick juices from a fruit pie? Sauces make eating a joy! They provide concentrated flavor in a thickened liquid form, with a pleasing texture and consistency that carries or compliments the flavor of the rest of the food. No matter if they're salty, spicy, savory, or sweet, sauces make foods richer and more special. There are many ways to thicken sauces,… Read more

How Does Atmospheric Temperature Affect the Water Content of Snow?

Science Fair Project Idea

Scientific Method

Are you a snow aficionado? What atmospheric conditions produce light, powdery snow, and what conditions produce heavy, wet snow? This project shows you how to use data from daily balloon soundings of the atmosphere and your own snow measurements to find out. Read more
